Paragraph

 1 1|      may, guided by antecedent perception, both pursue their food,
 2 2|   immediately concerned in the perception of sound consists of air,
 3 3|        say at once that visual perception is due to a process set
 4 5|     per se. The reason why the perception of such odours is peculiar
 5 5|      For this reason, too, the perception of odour [in general] effected
 6 5|        side-entrance."~But the perception of the second class of odours
 7 5|  Nature has bestowed their due perception of one of the two kinds
 8 5| sufficient provision for their perception of the one species of odour
 9 5|    human beings have for their perception of both.~But that creatures
10 5|  similar animals have an acute perception of their food by its odour.~
11 5|    plain, as well by immediate perception as from the arguments above
12 6|        if this is so] both our perception of them should likewise
13 6|       these are actualized for perception, always arrive first at
14 6|        this [viz. simultaneous perception of the one object by many]
15 7|    equal but heterogeneous, no perception of either will ensue; they
16 7|         But in such a case the perception of either stimulus in its
17 7|        all, or there will be a perception compounded of both and differing
18 7|      for we perceive them by a perception actually one. For an object
19 7|        which is perceived by a perception actually one, whereas an
20 7|         If then the actualized perception is one, it will declare
21 7|      be two; but [if so, their perception must be successive not coinstantaneous,
22 7|       and the same faculty the perception actualized at any single
23 7|      than such coinstantaneous perception [of one object, in one instant,
24 7|  Therefore, if coinstantaneous perception of the latter be impossible,
25 7|       logically annihilate the perception of both Objects and Time].~
26 7|   hence their actualization in perception is one; but if this is so
27 7|        engaged in simultaneous perception with one sense) is what
28 7|      Soul, that the faculty of perception in general is in itself
